TEM images of precipitate present in solution containing STNA15-ELP at (A) 3 h and (B) 8 days of incubation (inset 2 showing the high resolution TEM image with FAp planes visible). The 3 h precipitate is a nano-crystalline apatite. At 8 days the apatite has a needle-like form. The needles that were directly in contact had some co-alignment as seen in the SAED pattern (inset 1). The spherical particles, present at 8 days, were confirmed to be CaF2, from the SAED pattern (inset 3).
